Xcode/Stackview，堆栈视图中的空标签吓坏了? [英] Xcode/Stackview, empty labels freaks out in stack view?

问题描述

希望这里很简单.我有一些标签和文本字段.在它们之间，我想要一些空标签，如果需要，它们将是错误文本.但是当我尝试将其全部堆栈查看时，Xcode 缩小并且在 viewController 上看不到任何内容.我还需要更改什么才能使其正常工作吗?

hopefully an easy one here. I have some labels and text fields. Between them, I want some empty labels, which will if needed to be error texts. But when I try to stack view it all, Xcode zooms out and nothing can be seen on the viewController. Anything else I need to change for it to work?

在我点击堆栈视图之前，您可以在这里看到它的图片:

You can see a picture of it here before I hit stack view:

电子邮件标签和文本字段已经在堆栈视图中，密码、gentag 密码和标签/按钮也是如此.

The email label and text field are already in stack view, so are passwords, gentag passwords and label/button.

推荐答案

这显然是一个错误.我复制了你的问题.在将它添加到我的堆栈视图之前，我能够通过为每个空的间隔标签设置高度/宽度来解决它.这是没有意义的，因为当您将一个对象添加到堆栈视图时，它会失去它所具有的所有约束.尽管如此，它解决了问题:

This certainly appears to be a bug. I duplicated your issue. I was able to solve it by setting a height/width to each empty spacer label, prior to adding it to my stack view. This doesn't make sense because when you add an object to a stack view it loses all of the constraints it has. None the less it resolved the issue:
